IMPROVEMENT IN SULKV-HARROWS.

Specification forming part of Letters Patent No. 160,335, dated March 2,1875; application filed January 6, 1875.

To all whom it may concern:

Be it known that I, JOSEPH KIMBALL, of Pleasant Home, county of Polk andState of Nebraska, have in vented certain Improvements in Sulky-Harrows,of which the following is a specification:

This invention relates to that class of harrows which are supported onwheels, which v and use my invention, I will now proceed to describe thesame with reference to the accompanying drawing, in which Figure l is atop-plan View of a machine embodying my invention. Fig. 2 is a verticalsectional view on the plane of the line 00 00 in Fig. 1; and Fig. 3 isan elevation, rear.

Referring to the parts by letters, letter A represents the axle; B B,the supportingwheels, and D the tongue or draft-pole, stayed by ordinaryhounds d d. E E are the harrows, formed of diagonal bars 0 andtransverse bars 6, and provided with ordinary teeth 6. The harrows E areplaced on each side of the machine, and in such a manner that one of thewheels B stands in the central part of each harrow. The harrows areconnected to each other by bars F, which are pivoted to each other andto each barrow, so as to allow -of independent motion to a certainextent of each harrow. G is a curved bar attached centrally to thetongue, and g g are links by which the harrows E are attached to theends of the bar G. H H are levers, pivoted at h in a standard, h, fromthe tongue. I I are standards projecting upward from each end of theaxle. J J are transverse levers, pivoted centrally in the standards I,their inner ends journaled on the levers H, and their outer endscarrying each a bar, K. L L are rods journaled on the ends of the rodsK, and their lower ends attached to the harrows. M M are catches, theirlower ends pivoted to the axle A, and their central portions havingcatches m. N is the drivers seat, supported on a spring-bar, n, whichrises and curves backward above the tongue, and is provided at its rearend with a vertical bar, a, which extends downward and through aguide-loop, n, on the axle. The bar it is pierced with holes, throughwhich a bolt may be inserted to secure a cross-bar, P, as shown at Fig.3, when desired. Q is a double-tree mounted on the tongue, and to whichthe draft-animals are attached.

The operation is as follows: The driver from his seat may place his feetupon the levers H, in rear of their pivot-points h, and, by pressurethereon, may raise the harrows separately or both at once, and asdesired, to pass over obstructions, or for other purposes, and may, inthe same manner, raise them entirely above the ground and retain themthere for transportation, &c., by pressing over the catch-bars M, sothat the catches m will pass over the tops of the levers H.

When in operation it is desired to increase the pressure on the harrows,it may be done by the driver placing his feet on the levers H, forwardof the pivot-points h, in which manner he may, by pressure with hisfeet, regulate the pressure on the harrows for hard places in the soil,and for other purposes.

The levers H extend back far enough so that the driver may .walk andoperate the machine by hand, in which case the bar I? is put in place insuch manner as to sustain a portion of the downward pressure on thelevers H on the bar it, and hence on the spring seat-bar it, giving theadvantage of the spring'bar it thus to the easy motion of the harrows.

It will be obvious that, by hand as by feet, the rear ends of the leversH may be raised to increase the weight on the harrows.

By removing the harrow-teeth immediately in front and rear of the wheelsB, the machine may be used as a corn-marker.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The levers H H and J J, arranged to operate with the bars K, rods L,harrows E E, axle A, and wheels B B, substantially as described, and forthe purpose specified.

2. The drivers seat, combined with the levers H H and J J, bars K, rodsL, harrows E E, axle A, and wheels B B, substantially as described, andfor the purpose specified.
